Abstract: A cut lever apparatus that automatically actuates a lock lift assembly to either lock or unlock a coupler knuckle of a freight car coupler. The apparatus includes a cylinder member having a piston disposed therein. A bracket member is attachable to the freight car coupler to support the cylinder. A linkage member is connected to the piston of the cylinder and the lock lift assembly to convert a lateral motion of the piston to a curvilinear motion of the lock lift assembly to either lock or unlock the coupler knuckle. A valve member is connected to the cylinder for communicating a pressurized fluid to the cylinder when a predetermined signal is sent to the valve and preventing pressurized fluid from entering the cylinder in an absence of the predetermined signal. Pressurized fluid in the cylinder is vented to atmosphere when the valve shuts off supply of pressurized fluid thereto.

Abstract: In combination with a railway freight car coupler. A coupler has a knuckle side, and includes a knuckle, knuckle pin, and an apparatus for automatically pivoting and maintaining the knuckle full open position. The improvement comprises a coiled torsion spring which is capable of continuously exerting a predetermined force. A sleeve in combination with a flange is secured to the bottom end of the knuckle pin for attaching the torsion spring onto the coupler head. A support member is attached to the knuckle and cages one arm of the torsion spring which exerts a continuous force on the knuckle to rotate and maintain the knuckle full open position. A compression spring may be employed in place of the torsion spring in combination with a locking mechanism which, rigidly secures the knuckle and knuckle pin therebetween to prevent independent movement.

Abstract: In combination with a railway car hand brake, there is an apparatus for sensing the hand brake release comprising a housing and a mounting mechanism for attaching the housing to a cover of such hand brake. An actuating mechanism is disposed in the housing. A sleeve member is disposed on the actuating mechanism and includes a flange. A flexible connecting mechanism engages the sleeve member and a winding gear portion of the hand brake. A sensing mechanism is disposed in the housing and aligned with the actuating mechanism. A securement mechanism is disposed on the sensing mechanism and mounted on the cover of the hand brake. A compression member is disposed in the housing and engages the flange of the sleeve member, whereby an electrical or magnetic signal will be received from the actuating mechanism by the sensing mechanism.

Abstract: A device for providing self-lubrication to a slackless coupling system for a railway vehicle, specifically an articulated connector. The device comprises a self-lubricating member having a predetermined size and shape. The self-lubricating member is integrally formed from a non-stick material. The self-lubricating member has an inner surface and an outer surface, whereby such non-stick material will provide sufficient lubrication between the inner surface of the self-lubricating member, and a first surface of a spherical member coming in contact with the inner surface of the self-lubricating member, thereby allowing unrestricted movement of such spherical member there against, thus causing a reduction in L/V ratio when such self lubricating member is used in such coupling system.

Abstract: The present invention provides an improved TMX.RTM truck mounted brake assembly for applying a brake shoe force to a railway car wheels by interfacing with an axle motion III bogie. The improvement comprises a rack and pinion type hand brake mechanism integrally mounted on at least one truck bogie per railway car. The hand brake mechanism utilizes a plurality of gear/pinion arrangements to transmit the force applied at the drive wheel to the transfer lever disposed within the TMX.RTM truck mounted brake assembly to effect the brake application. The hand brake mechanism is disposed within the spatial confines of the TMX.RTM truck mounted brake assembly and axle motion III bogie. The brake beams of the brake assembly are of the open box construction to accommodate such hand brake mechanism. A visual indicator is provided to identify the hand brake in both fully applied and fully released positions.
